Claims.

This invention relates to locks. It is particularly directed to a key actuated lock.

An object of this invention is to provide an improved key actuated lock such as may be employed for locking folding gates and the like articles.

In former foldable gate locks such as described in Patent No. 1,651,394, issued December 6, 1927, the lock includes a bolt which projects from a housing and engages a keeper. When the gate is open a portion of the bolt is exposed. It has been found that vandals or thieves often tamper with the exposed Ibolt or break it so that the gate cannot be locked. It is hence another object of this invention to provide a lock of the character described comprising a housing provided with a chamber in which the bolt is mounted, and a keeper having a tongue insertable into the chamber when the lock is open, and said bolt being adapted to be rotated to a position where it engages the inserted tongue to lock the keeper against withdrawal from the chamber. With such construction the 'bolt is wholly housed within the housing and cannot be tampered with or broken to thereby prevent locking of the lock.

Yet another object of thisinvention is to provide a strong and durable lock of the character described which shall be relatively inexpensive to manufacture, sure and positive in operation, rugged in construction, and yet practical and enicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which Will be exempliiied in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention,

Fig. 1 is an elevational cross-sectional view of a, lock embodying the invention with parts in cross-section;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig.. l;

Fig. 3 is a front elevational view of the lock housing;

Fig. 4 is a rear elevational view thereof;

Fig. 5 is a rear perspective View of the rotary bolt;

Fig. 6 is a front perspective view thereof;

Fig. 7 is a perspective view of the key cylinder;

Fig. 8 is a cross-sectional view taken on line 8--8 of Fig. 1;

Fig. 9 is a view similar to Fig. 3 but showing the bolt in unlocked condition; and

Fig. 10 is a front elevational view of a folding gate provided with a lock embodying the invention.

Referring now in detail to the drawing, I0 designates a lock embodying the invention which may be used in a folding gate Il. The folding gate II comprises gates l2 and I3 of usual construction. The gates I2 and I3 comprise vertical end members I4 and I5 which are moved toward or away from each other to close or open the gate.. The lock I0 comprise-s a keeper I6 on member I4, and a housing I8 on member I5. Housing I8 may comprise a prisnratic block of metal fixed to member I5 by a pair of rivets I8a.

The keeper I6 is made of a fiat piece of metal and may be riveted, welded or otherwise attached to gate member I4. 'The keeper I6 has a portion 2li projecting beyond the gate member I4. Said portion 20 is formed with a T-shaped slot 2| forming a pair of symmetrical, opposed, hooked tongues 23 and 24 as shown in Fig. 1 of the drawing.

The housing I8 is formed with a horizontal opening 25, the axis of which is along the center line of keeper I6. The opening or bore 25 extends to the rear end of the housing but terminates short of the front end thereof. At the front end of opening 25 is an opening 26 co-axial therewith. The opening 26 has a diameter smaller than the diameter of opening 25. Housing I8 is also `formed with a vertical slot or opening 28 extending above rand below the bore 25 and opening 26. Opening 28 extends to the front surface of housing I8 but terminates short of the rear surface of said housing.

It will now be understood that` adjacent the front surface of the housing are formed a pair of diametrically opposed flanges or shoulders 38 for the purpose hereinafter appearing.

Disposed within bore 25 is a key cylinder 32 of any suitable construction. Within the key cylinder is a rotary member 33 formed with a flat forwardly projecting tongue 34. Upon turning the key 35 to open the lock, tongue 34 is moved to vertical position and when the key is turned to lock the lock, tongue 34 is turned to horizontal position. Key cylinder 32 may be fixed within bore 25 by means of a. pin 31 pressed through an opening 38 in one side of the housing.

Rotatably mounted within the forward end of bore 25 and in front of th'e key cylinder 32 is a bolt 40. Boltl 40 comprises a stem 4I formed with a transverse'slot 42 at its rear end receiving therethrough the tongue 34. At the lfront end of the stem 4I is an annular enlarged ange 43 formed at diametrically opposite sides thereof with notches 44. It will be noted thatbolt 40 is located between the rear surface 28a. of slot 2'8 and flanges 30. Flange 43 is adapted to contact the flanges 30. Flange 43.is cylindrical and thereforerotatablymounts the bolty within the front end of aszaoea 3 bore '25. Lips 30 prevent out of the h'ousing.

It will be noted that the notches 44 are aligned with the transyerse notch 42. Thus when the lock is locked, the notches 44 asl w'ell asthe notch 42 are in a horizontal plane. When the lock is the bolt from coming unlocked both the notches 44 and notch 42 areqv in vertical position.

Referring now to Fig. 1 of the drawing, it willg' be noted that the hooks 23 and 24'oan1enter the the notches 44 are in verticallyA aligned positions. When the tongues 23, 24 are inserted into slot 28 the head or ange 4 3 of the bolt will be disposed withinthe slot 2] of th'e keeper.
